I tried everything was proposed a few weeks ago but nothing worked (even
with -v -v -v -v -v, my document was not marked as deleted.)

So, here are three config files which are good enough to reproduce my
problem. (htmerge-problem.zip is zipped with WinZip but is readable with
the free unzip for Unix we could find on several web sites.)

I'm using locale: fr_FR (look at include.conf), it could be unconvenient
for you but I don't have any other short example for the moment (I could
try to find one which doesn't use accented words if you like.)
